Abstract
A vertical continuous coke oven is composed of several charring chambers and two combustion chambers at both sides, and features that the low-variation coal with large storage capacity can be used for in-situ conversion, deep processing and comprehensive utilization to continuously produce high-quality ferroalloy coke, and also can be used as the furnace for converting other materials.
Description
The utility model relates to a kind of pit kiln.
Present big-and-middle-sized pit kiln has industrial scale great machinery degree height, and the characteristics of Chemicals such as recyclable coal gas, tar, but because its scale of investment is big, strict to feed coal, limited application to small towns and small-sized coking enterprise, though occurred a collection of small-sized pit kiln in recent years, can, consume energy big, thermo-efficiency low, big for environment pollution, furnace binding intensity difference low, of poor quality owing to its coke output, no furnace retaining facility, converter life are lacked, are unfavorable for promoting the use of.
For remedying above-mentioned the deficiencies in the prior art, the purpose of this utility model is: transform on the spot for making coal deep processing comprehensive utilization, provide that a kind of coke output is big, quality good, thermo-efficiency is high, can reclaim coal gas and tar, environmental pollution is little, less investment, the construction period is short, usable reserves is big low rank coal, coking quantity-produced pit kiln separately.
The purpose of this utility model realizes in the following way:
Fig. 1 is the pit kiln overall schematic.
Fig. 2 is the front view of body of heater.
Fig. 3 is the A-A sectional view of body of heater.
Fig. 4 is the B-B sectional view of body of heater.
The utility model is designed to vertical structure for realizing the continuity production type of furnace, body of heater (1) is built on the steel platform (18), body of heater is made up of the independently upper and lower separately layer of several coking chambers (2) and coking chamber both sides combustion chamber (3), (4), and distribution chamber (5), horizontal quirk (6), fire grate brick (7), hot air vents (8) formation are just fired by level in every layer of combustion chamber; Be control combustion gas distributed uniform, vertically fire grate brick (7) is gone up, the other layout of hot air vents (8) regulate brick (9) along horizontal quirk (6), and is provided with and regulates peephole (14); Temperature for control coking chamber, combustion chamber is provided with thermometric pressure tap (13), and the thermometric utensil uses thermopair; For to the combustion chamber heat supply, coal gas air mixed burner (19) is set; For the thermal expansion of control body of heater prolongs converter life, furnace retaining post (17) is set around the body of heater, by upper, middle and lower tie rod (16) control, body of heater is provided with tie rod ditch (15); For reducing body of heater heat radiation and fireclay brick consumption, reduce body of heater weight, upper strata top of combustion chamber entity part is provided with thermofin (12) in resistance wall (10), the envelope wall (11), and resistance wall is used the red machine brick of 100#; Quenching is provided with the water jacket coke discharge box (22) of interior available cooled coal gas of case and water quenching to the pollution of environment in the coke sensible heat cancellation atmosphere in order to reclaim, and seals the coke discharge box end opening with water sealed tank; Raw gas atmosphere pollution when preventing coal, and utilize the waste heat preheating and drying in the raw gas to go into the wet coal of stove, improve the heat-up rate of coal charge, the coking chamber closed coal storage case (26) that is provided with suitable for reading, cut off by coal valve (28) control coal amount and with atmosphere, and the coal storage case adds explosive door and configuration coal bin base (25), and the coal bin base is provided with gas export control (27), and destructive distillation product raw gas is admitted to gas cleaning system thus; For there being certain coal amount before the coal, furnace roof coal bunker (29) is set, transport coal charge by climbing car (30).
Working process of the present utility model is: the coal charge of selecting 10～80 mm particle sizes, rise to furnace roof coal bunker (29) deposit by climbing car (30), the manually opened coal valve (28) every 15 minutes, to closed coal storage case (26) coal, coal charge is preheating to about 100 ℃ at this hot raw gas that comes that risen by coking chamber, drying is fallen most of moisture content, coal charge is by deadweight then, from top to bottom move on to coking chamber (2) epimere pre-heating temperature elevation district, it is softening to be decomposed very soon, continue to move down into coking chamber (2) middle part destructive distillation heating zone, the about 1100 ℃ of high temperature gas flows that entered by upper strata hot air vents (8) are heated to about 800 ℃, decompose remollescent coal grain top layer and form duricrust, enter the semicoke cure stage, the semicoke after the curing continues to move down into coking chamber (2) middle and lower part dry distillation area hypomere, the high temperature gas flow that is entered by other which floor hot air vents 8 is heated to more than 1000 ℃, semicoke maturation gradually is a coke, and coal charge is a coke from being preheating to destructive distillation ripe, about about 4.8 hours of whole process carbonization time.Sophisticated red-hot red Jiao continues to move down into coke discharge box (22) and is entered interior cooled coal gas of case and cold water sprinkling cooling, fall at last on the coke extractor (23) in the coke discharge box water sealed tank (24), decide rotating speed by coke extractor according to furnace temperature, the coke that the cooling back is about 60 ℃ is discharged, and is transported by the burnt car of fortune.
Coal charge is preheating in coking chamber, and water-gas that quenching produces in the dry distillation gas that destructive distillation produces, stove and the raw gas of being made up of the High Temperature Gas that hot air vents enters are together discharged from raw gas delivery line (27), enter gas cleaning system.
Coal gas part after the purification is back into the firing tunnel in coking furnace process pipe of stokehold, through branch gas tube (20) with by the combustion air of stokehold air process pipe, through air arm (21), while is just fired distribution chamber (5) primary combustion by the level that coal gas air mixed burner (19) mixed firing sprays into each layer combustion chamber (3), (4), just the coal gas of combustion is assigned to horizontal quirk (6) uniformly through fire grate brick (7), fully burning, enter coking chamber (2) through each hot air vents (8) again and rise, directly carry out flash heat transfer with the coal charge that moves down.The temperature adjusting of combustion chamber, coking chamber is undertaken by the orifice plate and the cock that reach the outer branch gas tube (20) of other adjusting brick (9) of hot air vents and stove, air arm (21) on the fire grate brick in the stove, and combustion chamber pressure should be greater than coking chamber pressure.
The utility model has the advantages that: adopt the method for internal heating to carry out continuous production, heat transfer process is the thermal convection of carrying out in the hole of hot gas between the coal grain, thermal radiation, thermal conduction complex heat transfer process, thermosteresis is little, the combustion heat is fully used, throughput, single hole coking chamber daily output amount of coke is 20～22 tons, be with more than 2 times of scale, coke quality is good, fixed carbon content is between 86～90%, coal gas, the coking chamber dry distillation area epimere that the generation of tar mainly takes place, second pyrolysis can not take place in tar, tar yield can reach 4.5～5% than higher; Wet coal at closed coal storage case preheating and drying, the sensible heat of recyclable part raw gas, quenching is carried out in stove, and the sensible heat of recyclable coke 60%, the thermo-efficiency of coke oven can reach more than 80%, do not constitute the pollution to environment simultaneously; Furnace binding is simple, and the refractory brick consumption is few, does not need capacity coke oven equipment, so less investment, and the construction period is short, and instant effect is suitable for the coal deep processing and transforms on the spot, and township and village enterprises and coking enterprise use.
